' ing lates or the like bythe use of a photograp ic process of the type in which symbols,

characters or the like to be printed are photographed singly and consecutively upon a sensitized surface, and constitutes a division of my application Ser. No. 589,365, filed Sept.

, With the object of allowing any desired number of styles of character such as roman, arabic, italic and so forth, the characters of each style, that is to say, the characters of each group or series are according to the present invention formed as light opaque stencils in series upon a flexible film so that it will be immediately seen that the number of available characters is almost unlimited as the flexible film can be of any desired length.

The invention is more particularly described with reference to the accompan ing drawing showing diagrammatically one orm of character matrix or strip.

The character matrix of the present invention comprises a long strip 1 of Celluloid or the like material having perfora'tions 2 along its edges by means of which it can be displaced lengthwise and accurately positioned relatively to rows of characters 8, 4, 5, upon it.

The character strip 1 has a number of alphabets in sequence upon it as shown arranglng with the individual characters normal to the length of the strip and in rows one above the other, the arrangement being preferably such that the capitals, for instance, are in the upper row, the lower case in the second row, and the peculiars in the third row. The film strip contains characters along its length corresponding to a number of different styles, such as modern, arabic, gothic, etc.

The film strip may have `a portion 6 of its surface in which are punched perforations 7 in three groups corresponding to the groups of characters 3, 4, 5, these punchings being adapted to operate pneumatic'ally or electrically the o eration of means for displacing a carriage caring a light sensitive surface by means lcorresponding to the body widths 4, 5, so thatthey canbe used as a mechanical Y meansof bringing the characters with optical precision into any desired position. l I declare that what I claim is 1. As an article of manufacture a flexible film strip having a number of alphabets each of a different type arranged lengthwise in sequence thereon. Y

2. As anarticle of manufacture a flexible film strip having a number of alphabets each of a different type arranged lengthwise in seguence thereon, the -individual charactersl being normal to the axial length ofthe strip.

3. As an article of manufacture a flexible film strip having a number of alphabets each of a different type in three rows comprising respectively the capitals, lower case and other characters, each arranged lengthwise in sequence thereon.

4. As an article of manufacture a flexible film strip having a number of alphabets each of a different type arranged lengthwise in sequence thereon, and mutilations on said strip for displacing or indexing the same.

5. As an article of manufacture a flexible film strip having a number of alphabets each of a different type arranged lengthwise in sequence thereon, and mutilations along the edges of said stri spaced accurately similar to the spacing o the individual characters thereon.

6. As an article of manufacture a flexible film strip having the characters of a number of alphabets arranged in sequence lengthwise thereon as light opaque stencils and groups of perforationsin the strip varying differentially in number according to the body width of the character to which they correspond and spaced similarly to the rows of characters.

7. As an article of manufacture a flexible film strip having the characters of a number of alphabets arranged in sequence lengthwise thereon as light opaque stencils and groups of perforations in the strip var ing differentially in number according to the ody width of the character to which they correspond and spaced similarly to the rows of characters,and arranged in a portion of the film strip parallel with that portion carrylng the characters.

8. As an article of manufacture, a flexible 'l film strip having a plurality of light rstencils of symbols and characters arranged thereon,a

and punchings in the strip in predetermined positions for effecting the spacing of the sheet to be printed by values corresponding to the punchings, said pnnchings being positioned in correspondence with the variable Widths ofletter spacing of the particular associated symbols'.

In Witness whereof, I have hereunto signed my name this 4th day of December, 1925.

EDGAR KENNETH HUNTER.
